Avast Free makes too much web traffic

Avast Free Antivirus / Premium Security
1

Hallo,
I want to ask if it is standard that avast itself, after all updates and actualizations done makes a lot of web traffic. I need to use my mobile data to connect laptop to internet, and I see bleeding of data because of avast doing … nothing. Literally using skype, browser, and bunch of other aps, the avast still makes some 95% of data transferred. And that is, at least for me, very bad statistics.

For now I just turned off the avast in firewall so it cannot connect to internet on all levels (service, program, …), because I don;t want to pay for dumb traffic.

So, what is the problem? is it standard or what is going on?

Thanks for explanation.

Avast acts like a local proxy, so that’s totally normal and explains the (misleading) stats.

That is what making it look like avast is using a lot of bandwidth, but it is just scanning the traffic from those applications.

The firewall isn’t causing any traffic as it just monitors the traffic from the apps that are sending/receiving data.

Thank you for answers. Just if I understand it correctly I’d like to tell it by my words:

Avast is not eating the data, it just sits on the port(?) and scanning data transferred through it. Therefore it looks like Avast eats the data, but that is not true and the data are eaten by other programs.

Right?

Exactly.

Yes that is correct.
See the firewall as a doorman at a busy café.
He only checks who is going in/out.
He is not one of the many visitors (=data traffic)

Thanks for good news:)

Still there is the question which program eats so much data, but that is different story.

You’re welcome.

  • Check the data transfer
  • Disable (or even remove) one of the app’s
  • Check the data transfer

You should be able to find out what is using how much bandwidth this way, or at least got a indication.
Skype is known to use a lot.
A browser (unless you download a lot through it), is not using much bandwidth normally.

Well, I use for watching data transfers GlassWire, which I think is good in that. Except the fact, that it shows Avast eats the data. So, using it I cannot say what program does it really eat.

But I will figure out.
